In a Q&A on Xbox Wire, executive producer Josh Bridge said Capcom Vancouver had kept an eye on feedback as it prepared the game's first major update.

"We also looked at various performance improvements," he said. "In this type of big open-world game with tons of zombies and the ability to do whatever you want to do, like stacking a bunch of things and blowing them up, we knew we had to improve on those high points and tighten the gameplay experience. Finally, there were some stability issues that we dealt with to make everything that much smoother."

The update also fixes issues related to Achievements, UI updates and SmartGlass, as well as adding a new impulse trigger feature that lets players know when they're low on ammo.

At 13GB it's a huge title update. "With all of the fixes and everything, it's a large update of about 13 gigs, but we really recommend getting it to ensure compatibility with the online players and all of the upcoming add-on content that's coming out shortly as well," Bridge said.

Operation Broken Eagle is the first episode in the Untold Stories of Los Perdidos DLC series. In it you control Spec Ops Commander Adam Kane, who is on a mission to capture the missing President of the United States. It costs £7.99 and for that you get a new mission, five new weapons, one new combo weapon, one new vehicle, a new clothing outfit plus more Gamerscore. You can carry experience points gained in the DLC back to Dead Rising 3.

The £23.99 Dead Rising 3 Season Pass includes Operation Broken Eagle and the three upcoming content packs - what amounts to a 25 per cent discount compared to buying them individually.

Each DLC content pack is single-player only, but their weapons and vehicles can be brought into the main game for co-op.

Meanwhile, Microsoft hailed Dead Rising 3 as a sales success. It said it was now the third best-selling Xbox One game and the fifth best-selling game across next generation platforms.
